VALVE-GRINDING OUTFIT.

Application filed June 12, 1922. Serial No. 567,549.

[0 all whom it may concern:

Be it known that I, WILLIAM RrroHIE, a citizen of the United,States,residing at Port Orchard, county of Kitsap, and State of Washington,have invented a new and useful Valve-Grinding Outfit; and I do herebydeclare that the following is a full, clear, and exact specification,such as will enable others skilled in the art to which it appertains tomake and use the same.

The invention is a device for grinding motor vehicle valves which may becarried in a persons pocket and operated by hand.

The object of the invention is to provide a device, with a small casefor holding it,

which may be placed on top of a valve, and which will cause the valve torotate or raise, as it is rotated or raised.

With these ends in view the invention embodies a cylindrical shapedpiece of material with one end of a smaller diameter than the other, aleather disk held on the larger end by two pins whose heads projectbeyond the disk and a case for holding the piece of material, which casewill'also hold an abrasive powder.

Other features and advantages of the invention will appear from thefollowing description taken in connection with the drawings, whereinFigure l is a cross section through thecontainer.

Figure 2 is a plan view with the container removed.

Figure 3 is a view with part broken away showing the device as it wouldbe used.

In the drawings I have shown my device as it would be carried in Figure1, wherein numeral 1 indicates the cylindrical piece of material whichhas a large end 2 and a small end 3 forming a handle. A leather disk 4is held to the large end by the pins 5, which have shoulders 6 on them,for holding the disk, while the outer ends of the pins project outward.This device is held in the container 7, which has a cap 8 on it, and inthe lower end of which an abrasive powder 9 may be placed. A flat disk10 with a hole in its center to fit tightly around the handle at the end3 of the piece of material 1 may be inserted in the container to form acom partment in the bottom for holding the abrasive powder. Thiscontainer may be made in any desired shape, or the upper end 3 of thepiece of material 1 may he made in any desired shape, without departingfrom the spirit of the invention.

The construction will be readily understood from the foregoingdescription. To use the device the piece of material 1 may be taken fromthe container in which it may he carried, and placed on top of the valveas shown in Figure 3, after the cylinder head casting has been removedand also the pin removed from the lower part of the valve stem. Theleather disk should be thoroughly saturated with oil so that a thin filmof oil will displace air between the disc and the top of the valve whena slight pressure is applied and this will make it possible to raise thevalve through suction or adhesion by lifting the handle. A small amountof the abrasive powder, mixed with oil, will then be placed around theedge of the valve, and as the valve is lifted by means of the handle,this will work in between the beveled surface of the valve and the valveseat, then as the valve is rotated by twisting the device with the thumband forefinger, as the pins on the end of the device fit into holes inthe top of the valve, the valve will revolve and be ground to fit itsseat.

Having thus fully described the invention what I claim as new and desireto secure by Letters Patent, is

1. In a valve grinding device a cylindrical shaped piece of materialwith the upper portion of a somewhat smaller diameter than the lowerportion, a fibrous disk at the end of the lower portion, and pins withwashers, around them that project beyond the fibrous disk.

2. In a valve grinding device a cylindrical shaped piece of materialwith the upper portion of a somewhat smaller diameter than the lowerportion, a fibrous disk at the end of the lower portion, and pins thatproject beyond the fibrous disk.

3. In a valve grinding device a cylindrical shaped piece of materialwith the upper porlower portion, a fibrous disk at the end of the lowerportion, andpins with shoulders on them that are drive-n through thefibrous washer and into the cylindrical shaped piece of material forholding the fibrous disk and that are adaptable to engage openings inthe upper sides of the valves.
